First-in-history: Scientists at CERN will attempt to transport antimatter
15 Mar 2026

Scientists at CERN, the European particle physics laboratory near Geneva, are preparing for a groundbreaking experiment.

They plan to transport antimatter, one of the most exotic materials on Earth, for the first time ever.

The test run is scheduled for later this month and will involve a one-ton device containing about 1,000 antimatter particles (antiprotons).

Journey around CERN campus
Nature's enigma

Antimatter is a highly volatile substance that explodes into energy when it comes into contact with normal matter.

The upcoming test run will be a 20-minute journey around the CERN campus, with all eyes on the precious cargo.

If successful, this could open up possibilities for transporting antimatter to other labs for precision measurements, potentially unlocking secrets about why our universe is made of matter instead of these strange mirror particles.

Why is antimatter important?
Research implications

Dr. Christian Smorra, a physicist at CERN, emphasized the importance of antimatter in understanding the universe's composition.

He said, "A core question we want to understand is where did matter come from. And then, if you know about antimatter, it's natural to ask, why is that not here?"

This research could help explain why our universe is dominated by matter instead of its mirror counterpart, antimatter.

Antimatter in science fiction and reality
Cultural references

Antimatter has been a staple in science fiction, powering the USS Enterprise's warp drive and photon torpedoes in Star Trek.

However, the real-world application of antimatter is much more mundane.

For instance, bananas emit antiparticles through potassium decay, making them natural antimatter emitters. But these emissions are not enough to study the universe's composition.

History of antimatter discovery
Scientific breakthrough

Antimatter was first predicted in 1928 by physicist Paul Dirac, who combined quantum theory with special relativity.

The first antimatter particle, an antielectron or positron, was detected four years later by Carl Anderson at Caltech.

Since then, scientists have confirmed the existence of various antiparticles and their potential to form anti-atoms and anti-molecules.

What is the Antimatter Factory?
Experimental plans

CERN's Antimatter Factory produces antiprotons by smashing high-energy protons into a dense metal target.

These antiprotons are then slowed down and captured in an antimatter trap for further study.

However, the facility isn't ideal for precision measurements due to powerful fields used in the deceleration process.

To overcome this, researchers plan to transport the trapped antimatter to other labs where more precise measurements can be conducted.

How do you transport antimatter?
Transport logistics

Transporting antimatter is no easy feat.

The trap has to be engineered to prevent any contact with normal matter, which is achieved by keeping it under ultra-high vacuum and cooling it to -269 degree Celsius.

Strong magnetic and electric fields are then used to keep the antiprotons in the center of this cryogenic chamber.

These precautions are necessary even for minor disruptions during transit, like hitting a bump or sudden braking.
